Description

HISTORY OF THE APPLICATION

The present application is a continuation of co-pending application by the present Applicant for U.S. Letters Patent entitled "Manual Massage Instrument" having Ser. No. 194,492 which was filed Oct. 6, 1982, now U.S. Pat. No. 4,409,967, issued Oct. 18, 1983.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a manually operated massage instrument or appliance designed to cause a localized hyperaemia in the areas of the skin subjected to the massage. This localized hyperaemia consists in a congestion of the blood due to an activation of the underlying circulation, and facilitates the penetration of suitable substances. It is possible, therefore, to profit from this effect in particular in the field of cosmetics, in order to enable penetration of various creams or lotions into the area of the skin which has been congested by massage.

2. Description of the Prior Art

Present massage instruments include the friction glove and the massage brush, the latter having a plurality of spikes or points on its active surface which, on contact with the skin, cause a slight depression in the skin and consequently a localized hyperaemia.

In the French Patent Application No. 78-12063 filed on Apr. 24, 1978, (now published as French Pat. No. 2,424,022 issued May 24, 1982) there is disclosed a massage brush whose active surface is provided with asymmetrical spikes made of an elastically deformable, flexible material each having a concave portion and an opposite convex portion. The above-mentioned asymmetrical spikes in effect have a greater bending stength when their convex portion is used and a lower strength when their concave portion is used. In addition, the spikes are disposed facing away from one another, i.e. one spike having its concave portion facing in one direction is adjacent to a spike having its concave portion facing in the other direction.

The above massage instrument provides a double advantage: in the first instance, the efficiency of the skin massage is improved greatly in comparison with the massage obtained by known massage instruments such as a friction glove. In effect, the friction on the skin caused by spikes having alternating zones whose bending strength in the direction of displacement of the applicator is high and zones whose bending strength in the same direction is lower, causes on the sking the formation of wave-like or sinuous depressions which are displaced on the skin simultaneously with the massage instrument. In addition, as the spikes are made of an elastically deformable, flexible material, a brush of this type allows forceful massage of the skin without the risk of lesions or abrasions of the epidermal layers whilst adapting completely to the various morphologies of users.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide yet another massage instrument having spikes which are preferably symmetrical and which have alternate less flexible and more flexible portions. According to the invention, the spikes are constituted by non-intersecting plates which have, on one hand, a higher bending strength and consequently a "harder" contact on the skin if the faces of the plates constituting the spikes are used and, on the other hand, a lower bending strength and consequently a "softer" contact if one of the sides of the plates of the spikes is used. The spikes all have the same shape but are disposed with at least two different angular orientations, so that in the case of rectilinear massage the region of the skin on which the massage instrument of the invention is displaced is subjected to the action of alternating hard and soft spikes.

The present invention therefore provides a massage instrument for massaging the skin, on at least one active face of which instrument there are provided a plurality of projecting spikes made of a flexible, elastically deformable material, wherein the spikes are constituted by non-intersecting plates and are distributed in accordance with the angular orientation of their plates in at least two groups, the spikes of a same group being disposed, on the active face of the instrument, so as to alternate with the spikes of another same group.

In a preferred construction, the spikes are constructed in one piece with their support from a flexible, rubbery material; the plates constituting the spikes are substantially disposed at right angles on their support and have the shape of the segment of a circle which is connected by its chord to the support; and the surrounding surface of the face of the plates belonging to each spike has substantially the shape of a spherical portion. The spikes are constituted by non-intersecting plates which are substantially parallel, the plates of the spikes of a same group being orientated angularly with respect to the plates of the spikes of another same group. The spikes are preferably disposed in four groups, the plates of the spikes of a same group being orientated at 45° or a multiple thereof with respect to the plates of the spikes of another same group.

In the present invention, thereof the spikes may be equally well disposed in substantially parallel rows or along wave-like lines; two wave-like lines then being in phase opposition, or in concentric circles.

The massage instrument of the invention may comprise a massage brush, whose flexible support for the spikes is inserted within a rigid frame which may or may not be connected to a handle; the massage instrument may alternatively be a massage glove, i.e. a flexible bag on at least one of the surfaces of which project the spikes defined above. The massage instrument of the invention may be used not only for massage but also for the simultaneous washing of the skin. In this case, as disclosed in the first French Application of Addition No. 78-34330 filed on Dec. 6, 1978, the flexible support which bears the spikes may be provided with perforations and associated with a container designed to contain a hydrosoluble product, for example a bar of soap.

DETAILED DESCRIPTION OF THE DRAWING

FIG. 1 is a plan view of a massage brush in accordance with the invention; and

FIG. 2 is a perspective view, on an enlarged scale, of one of the spikes of the brush of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1 and 2 of the drawing show an embodiment of a massage brush according to the invention. The appliance has a frame 20 integral with a handle 30. The frame 20 is provided with a substantially elliptical cavity within which there is mounted a flexible support 21. Most advantageously, four groups of

spikes

22a, 22b, 22c, 22d are provided and project from the flexible support 21. The

spikes

22a, 22b, 22c, 22d are integral with the flexible support 21 and are made from a rubbery material.

The spikes are disposed in a lattice having a square mesh on the flexible support 21. The

spikes

22a, 22b, 22c, 22d, all have the same shape, and only their relative angular orientation is different. The

spikes

22a, 22b, 22c, 22d each comprise four substantially parallel plates 23 connected at right angles to the flexible support 21. Each plate has the shape of the segment of a circle which is connected by its chord to the flexible support 21. The surrounding surface of the face of the four plates 23 of a spike has the shape of a spherical portion. The plates 23 have, in the vicinity of their ends, a slightly increased thickness.

As can be seen from FIG. 1, the plates of the spikes 22a are parallel to the longitudinal axis 24 of the brush, while the plates of the

other spikes

22b, 22c and 22d are oriented as shown. The plates 23 of the spikes of a

same group

22a, 22b, 22c, 22d are orientated at 45° or a multiple thereof with respect to the plates 23 of the spikes of another group. The spikes of a same group alternate with spikes of the other groups on the flexible support 21.

If the massage brush shown in FIGS. 1 and 2 is displaced parallel to its axis 24 on the sking, the action of the spikes 22a is made on the face of the plates 23, whilst the action of the spikes 22c is made perpendicularly on the sides of the plates 23. The action of the

spikes

22b and 22d also takes place laterally but with an angle of incidence of 45°. The plates 23 of the

spikes

22b, 22c, 22d are consequently acted upon laterally and therefore have a lower bending strength than the plates of the spikes 22a which are acted upon by their face. Thus, by displacing the massage brush parallel to its axis 24, the skin comes into contact with the spikes 22a which appear "harder" than the

spikes

22b, 22d which are themselves slightly harder than the spikes 22c.

A very good massage action is produced by the brush appliance embodied as shown.

It should also be noted that the brush appliance here involved, as a result of the flexible material from which the

spikes

22a, 22b, 22c, 22d are made and as a result of the rounded shape of the non-intersecting plates which constitute them, are unable to cause either abrasion or destruction by friction of the epidermal layers, even if energetic massaging is carried out.

It should be understood that the embodiments described above are in no way limiting and may include any desirable modifications without departing from the scope of the invention.
